Abstract: A thimble shaped burner is made of a porous foam metal material and is adapted to be mounted on the interior of a plenum chamber receiving a fuel/air mixture under pressure. The fuel/air mixture infuses into the interior of the thimble shaped burner body and exits from it through a burner port in a support structure where the fuel/air mixture that has been infused through the burner body is ignited. The burners are typically used in multiples and are mounted by means conventional fasteners passing through reinforced mounting flanges on the interior of an air fuel plenum chamber. Flame lift off is reduced or eliminated by particular configurations and dimensions of annular metal washers that are used in association with the burner bodies for mounting purposes.

Abstract: The present invention relates to a candle blower. More specifically, the present invention is an automated candle blower programmable to direct a flow of air to the general position of a flame on a burning candle.

Abstract: One flexible windproof candleholder, which is composed of upper-open cylinder candleholder with gap at its side to change candle, a slide cover that covers onto periphery of candleholder and canister cover with light holes that covers onto interior of candleholder; wherein protruding stopper ball is respectively set at external and internal rim of bottom section of candleholder; concave parts made at lower rim of slide cover and canister cover can be used for block, so, slide cover moves down to envelop gap, wind may not blow candle; as slide cover and canister cover respectively move down to periphery and interior of candleholder, slide cover is pushed against upper cover of canister cover so that internal space of candleholder is sealed, the burning candle may extinguish itself due to lack of oxygen, canister cover slides upward along vertical runner setting in symmetry inside candleholder by stopper ball protruded at external low section, meanwhile, slide cover also slides upward to upper section of candle

Abstract: An oxygen injector assembly for directing substantially pure oxygen into the path of an effluent or exhaust stream from a primary reformer process for mixing of the oxygen with the effluent, the assembly comprising an oxygen delivery tube for discharging the oxygen into the path of the effluent, and a cooling jacket disposed around the outer periphery of the delivery tube for moderation of the ambient temperature conditions surrounding the oxygen injector assembly and thus compensating for the increased temperature conditions created by the mixing of the oxygen with the effluent in lieu of mixing air therewith.

Abstract: A fire-extinguishing device for an open-type oil burner is disclosed which is capable of effectively preventing the discharge of bad odor to a room due to unburned fuel oil gas at the fire-extinguishing of the oil burner. The fire-extinguishing device includes a damper for closing, at the fire-extinguishing, an opening of a combustion cylinder construction of the oil burner through which combustion gas is discharge to a room. The damper or combustion cylinder construction may be provided with an oxidation catalyst plate through which combustion gas is discharged to a room at the fire-extinguishing, so that unburned fuel oil gas may be removed by means of the catalyst plate.
